A follow-up to the website-only boot fix in 17.9.1 — that fix was incomplete, and a site running without the Umbraco backoffice (a delivery-only/website tier, common in load-balanced setups) could still fail to start.

• Fix: on a website-only boot, several parts of Translation Manager (the link updater, the property copier, and Xliff file handling) still tried to register services that depend on the backoffice, and Umbraco's own health-check discovery found Translation Manager's health checks regardless of any of our own checks. Both are now skipped correctly, so a website-only site starts cleanly
• Build: this package now ships with a matching, current version of its Xliff serialization component rather than an older one pulled in indirectly through a connector
